Potential, not guaranteed (subject to planning + regs). Estimate from the EPC certificate — verify room sizes against the floorplan before offering.
How we calculated this
floorplan shows 6 habitable rooms (4 beds + 2 reception(s)) in 90 m²; convert 1 spare room(s) to bedrooms, keeping one reception as the lounge → up to 5 lettable rooms; sized to West Northamptonshire adopted standard (6.51/10.22 m²; Northampton BC Landlord's Guide to Amenities and Facilities for HMOs (adopted for Northampton & Daventry area; legacy district standards under review for unification)); adds ~£601/mo; loft conversion may add 1-2 further rooms (subject to head height/planning — not counted); mandatory HMO licence (5+ persons, England); Article 4 — planning permission needed
Pro members see the floorplan with every convertible room outlined in green. Verify room sizes before offering.

Projections use documented assumptions (local room rates, typical conversion costs, 75% LTV at 5.5%, indicative regional valuation yields) and each council’s published HMO standards. Not financial advice. Verify room sizes, licensing and planning with the council and a surveyor before purchase.
